Ducks are omnivores, which means they have a varied diet. From aquatic plants, small fish, and insects to grains and seeds, ducks will dabble in a bit of everything. Their diet can vary based on their habitat, age, and the availability of food. But, can ducks eat onions?
No, ducks can’t eat onions because they contain thiosulfate, which can cause hemolytic anemia.
In this article we will learn more about why ducks should not eat onions.
Why Can’t Ducks Eat Onions?
- Allium Family: Onions, as many of us know, belong to the Allium family, which also includes garlic, leeks, and chives. These plants contain a compound called thiosulfate. While this compound is harmless to humans (and indeed, gives onions their characteristic flavor), it’s a different story for our quacking comrades.
- Thiosulfate: Thiosulfate can cause oxidative damage to red blood cells in ducks, leading to a condition known as hemolytic anemia. In simpler terms, the red blood cells that transport oxygen around the duck’s body can burst, leading to several health problems. Symptoms of this condition include lethargy, weakness, rapid breathing, and even death in severe cases.
- A Duck’s Digestive System: Ducks have a unique digestive system that’s optimized for a diet of aquatic plants, small fish, insects, and grains. Introducing onions, especially in large quantities, can disrupt this delicate balance. Their stomachs, or more accurately their gizzards, are not equipped to handle the strong compounds found in onions.
Can Ducklings Eat Onions?
No, ducklings can’t eat onions either. Onions belongs to the allium family, which are known to contain thiosulfate, which is very dangerous for ducklings. It can effect the ducks breathing leading to death in worst cases.
